STD 4

INSTALLATION

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION

IMPORTANT:

To enable the installer to make a quality installation and to minimize installation time, the following suggestions and tests should be done before the actual unit installation is started:

CAUTION:

EQUIPMENT DAMAGE

DO NOT plug in or energize this appliance until all Installation Instructions are read and followed. Damage to the Brewer will occur if these instructions are not followed.

CAUTION:

UNSTABLE

EQUIPMENT HAZARD

It is very important for safety and for proper operation that the brewer is level and stable when standing in its final operating position. Provided adjustable, non-skid legs must be installed at each corner of the unit. Failure to do so will result in movement of the brewer which can cause personal Injury and/ or damage to brewer.

NOTE: Water supply inlet line must meet certain minimum criteria to insure successful operation of the brewer. Bloomfield recommends 1/4" copper tubing for installation of less than 12 feet and 3/8" for more than 12 feet from a 1/2" water supply line.

REFER TO EXPLODED VIEWS PAGES 18 thru 22 FOR COMPONENT NAMES/NUMBERS

Unpack the unit. Inspect all components for completeness and condition. Ensure that all packing materials have been removed from the unit.

Verify that the Spray Head Gasket and Spray Disk are properly installed.

LEVELING THE UNIT

Verify that an adjustable leg is installed at each corner of the brewer, and that a rubber foot is installed on each leg.

Set Brewer in its operating location. Level the Brewer. A spirit level should be placed on the top of the unit, at the edge, as a guide when making level adjustments.

Level the unit from left to right and front to back by turning the adjustable feet. Be sure all four feet touch the counter to prevent tipping.

PLUMBER’S INSTALLATION INSTRUCTIONS

IMPORTANT: This equipment must be installed to comply with all applicable federal, state and local plumbing codes and ordinances; specifically: The Basic Plumbing Code of Building Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

Brewer should be connected to a POTABLE WATER, COLD WATER line. Flush water line before connecting to Brewer.

DO NOT use a saddle valve with a self-piercing tap for the water line connection. Such a tap can become restricted by waterline debris. For systems that must use a saddle tap, shut off the main water supply and drill a 3/16” (minimum) tap for the saddle connection, in order to insure an ample water supply. Remember to flush the line prior to installing the saddle.

The brewer must be installed on a water line with average pressure between 20 PSI and 90 PSI. If your water pressure exceeds 90 PSI at anytime, a pressure regulator must be installed in the water supply line to limit the pressure to not more than 90 PSI in order to avoid damage to lines and solenoid.

A water shut-off valve should be installed on the incoming water line in a convenient location (Use a low restriction type valve, such as a 1/4-turn ball valve, to avoid loss of water flow thru the valve.

913 75937 Owners Manual McDonalds Decanter Brewer 8718 & 8738

INSTALLATION (continued)

The water line must terminate in a 3/8" MNTP quick-disconnect fitting, which will connect to the provided flex line. See Figure 2 below.

Fig. 2 Water Supply Installation

In some areas, local codes require a backflow preventer (check valve) to be installed on the inlet water line. If a backflow preventer is used, you must install a water hammer arrester in the incoming line, between the backflow preventer and the brewer inlet, as far away from the brewer as space will allow. This will relieve the excessive back pressures that can cause faucet leaks and solenoid malfunctions.

ELECTRICIAN’S INSTALLATION INSTRUCTIONS

REFER TO ELECTRICAL SPECIFICATIONS - Page 1 Check the nameplate to determine correct electrical service required for the Brewer to be installed.

IMPORTANT: Before connecting to electricity, make sure automatic brewers are connected to the water supply and tank is filled.

Remove front panel to access terminal block. Model 8717 requires a 120/240 volt 3-wire (L1, L2, Neut) plus

Gnd 30 amp circuit. Model 8737 requires a 2-wire (L1, L2) plus Gnd 30 amp circuit. Flexible conduit is recommended for electrical connection to

allow brewer to be moved for cleaning underneath. Flexible or rigid conduit must be connected to the brewer with a

suitable strain relief (provided by electrical contractor).

WARNING:

SHOCK HAZARD

Brewer must be properly grounded to prevent possible shock hazard. DO NOT assume a plumbing line will provide such a ground. Electrical shock will cause death or serious injury.

IMPORTANT:

Supply power must match nameplate for voltage and phase. Connecting to the wrong voltage will damage the brewer or result in decreased performance. Such damage is not covered by warranty.

IMPORTANT: Do not connect brewer to electrical power until you are ready to fill the tank. See instructions on page 6.

IMPORTANT: The ground lug of the brewer must be connected to a suitable building ground.

OPERATION

Fig. 4 Brewer Operation Diagram

IMPORTANT:

Tank must be full of water before connecting brewer to electrical power. Heating elements will be damaged if allowed to operate without being fully submerged in water. Damage caused by operating the brewer without water in the tank is NOT COVERED BY WARRANTY.

A. START-UP

For initial start-up, or if the brewer has not been used for an extended period of time:

♦ Be sure spray disk and brew gasket are properly installed in the brew head.

♦ Be sure the water supply is properly connected and the water supply valve is turned ON.

♦ Be sure the WATER TANK IS FILLED BEFORE energizing the tank heater THE WATER TANK MUST

BE FILLED. Place an empty decanter under the brew head. With the TANK HEATER SWITCH OFF, press the START BREW SWITCH. Run at least three full brew cycles, or until water flows from the brew head. When water stops dripping, empty the container.

Once the tank is full of water, press the TANK HEATER SWITCH to ON. The heating elements will begin heating the water in the tank. When the water has reached the proper temperature, the “READYTO BREW” light will go glow.

913 75937 Owners Manual McDonalds Decanter Brewer 8718 & 8738

WATER HEATER

Water temperature is sensed by a thermobulb inserted into the water tank. This temperature signal is fed to the thermostat, which controls line power to the heating element.

The setpoint temperature is adjustable at the thermostat.

The element is protected from overtemperature by a hi-limit thermostat.

WATER FLOW

AUTOMATIC OPERATION

Pressing BREW button energizes the solenoid valve, allowing water from an external water supply to flow into the basin pan and then into the hot water tank. This forces an identical amount of hot water out of the tank and through the spray head into the brew chamber

The solenoid uses a flow control device so that flow is consistent between 20 p.s.i. and 90 p.s.i.

Length of time the solenoid is open is controlled by the timer.

HOT WATER FAUCET The faucet water coil is submerged in the hot

water tank and draws heat from the brew water. Water going to the water coil is not controlled by the solenoid valve.

The faucet is at supply water pressure any time the faucet shut-off valve is OPEN.

BREWING COFFEE

CAUTION:

BURN HAZARD

Exposed surfaces of the brewer, brew chamber and decanter may be HOT to the touch, and can cause serious burns.

CAUTION:

BURN HAZARD

To avoid splashing or overflowing hot liquids, ALWAYS place an empty decanter under the brew chamber before starting the brew cycle. Failure to comply can cause serious burns.

CAUTION:

BURN HAZARD

After a brew cycle, brew chamber contents are HOT. Remove the brew chamber and dispose of used grounds with care. Failure to comply can cause serious burns.

NOTE: Water for the hot water faucet is heated in a coil inside of the water tank. Use of the faucet will not affect the volume of water delivered for a brew. However, overuse of the faucet during a brew may lower the temperature of the brew water.

A. PREPARATION

Place one (1) genuine Bloomfield paper filter in the brew chamber. Add a pre-measured amount of fresh coffee grounds. Gently shake the brew chamber to level the bed of grounds. Slide the brew chamber into place under the brew head.

B. AUTOMATIC OPERATION BE sure “HEAT” light is not lit.

Fig. 7 Brew Chamber

Place the appropriate EMPTY decanter in place under the brew chamber.

Press the “BREW” switch. The solenoid will open for an amount of time determined by the timer setting, admitting a measured quantity of water into the tank.

Inlet water will displace a like amount of heated water from the tank. The hot water will be forced into the brew head where it will spray over the bed of grounds. Freshly brewed coffee will begin to fill the decanter under the brew chamber.

At the end of the brew cycle, some time will be required for all water drips out of the brew chamber as coffee. When the flow and all dripping stops, the coffee is ready to serve.

Discard the contents of the brew chamber and rinse it in a sink. When the ”READY TO BREW” light comes on, the brewer is ready for another brew cycle.

C. WARMERS Press either the MAIN warmer switch to energize the main warmer,

or the FRONT or REAR warmer switch to energize an auxiliary warmer. Set the filled decanter on the selected warmer to keep it warm.
